Natto-Cat

Natto-Cat is a unique Boulderdash style arcade game. You play as RB51, a half robot / half cat agent searching underground caves for cat snacks. Adversaries include walking, exploding custards, force-fed exploding rabbits, and expanding green peas.
When enemies explode, they splatter blood (or custard) on surrounding objects, so it is a bit violent. These splatter effects can be turned off by editing a prefs file.
There are 25 caves (and 6 intermissions). There are 3 difficulty levels for each cave, the highest of which is extremely challenging.
Currently, only a Windows py2exe binary is available.
